COLLAPSIBLE TUBE DISPENSING DEVICE Filed April 25, 1958 INVENTOR ATTO R N EYS vide a device of the Patented Feb. 21, 1939 UNITE? EPA-TENT.

3 Claims.

My invention relates to devices for dispensing paste and the like from tubes and more particularly to collapsible tubes.

One of the principal objects of my invention is to provide a device for receiving a collapsible tube equipped with means for dispensing the paste from said tube when the device is operated.

Another object of my invention is to provide a device of the above described character capable of being operated in a manner where a desired amount of paste or the like may be dispensed from the tube, the amount thus dispensed being under the control of the operator.

A further object of my invention, is to proabove described character which is simple in construction, durable in use, eflicient in operation and economical in manufacture.

Other objects and advantages will be apparent from the following description, appended claims and annexed drawing.

Referring to the drawing wherein like reference characters designate like parts throughout the several views:

Figure 1 is a top illustrating the same plan view of my invention in open position to receive a collapsible tube.

Figure 2 is a vertical section of my invention.

Figure 3 is a view similar to Figure 2 illustrating a collapsible tube applied thereto, the parts of the device being in closed position.

Figure 4 is a rear elevation of the device, partly in section, showing the pivot construction.

Figure 5 is a sectional view taken on the line 5-5 of Figure 4.

Figure 6 is a side elevation illustrating the tube inserted between the jaws of the device and in partly collapsed position.

In practicing my invention I employ a base section 5 constituting a stationary jaw and which is equipped with a floor 6 and vertically extending side walls 1. Pivotally mounted between the sides 1 of the base is a movable jaw 8, said jaw 8 being fashioned with a tube engaging face 9 and a forwardly extending lip I constituting a finger piece for operating said jaw as hereinafter described. The floor 6 of the jaw is fashioned with a transversely extending groove ll, adjacent the rear end thereof, for registry with a similar shaped transversely extending projection l2 formed on the face 9 of the jaw 8 for a purpose hereinafter described.

The rear end l3 of the jaw 8 is fashioned with a transversely extending opening M which receives therein a transversely extending pivot pin l5 having ends mounted in the sides I of the jaw 5. The pivot pin l5, intermediate of the sides of the jaw 8, is formed with an offset arouate portion I6 engaging the longitudinally extending tension pin l'l extending through the opening [4 from the rear end of the jaw 8 thereby maintaining the offset section l6 of the pin IS in engagement with the lower section of the opening I l. The opening I4 is of an elongated configuration in cross section to permit the pivot pin l5 to be disposed therein with the offset section I 6 extending below the major axis of the pivot pin.

Obviously, this construction permits the jaw 8 to move upwardly relative to the jaw 5 due to the resiliency of the pin I 5.

A collapsible tube 20 of ordinary construction is inserted between the walls I of the jaw 5 and the movable jaw 8 pivoted downwardly thereon to engage the upper outer face of the tube. In this position the projection I2 serves to urge a portion of the rear section downwardly within the groove I I and thereby lock the tube between the jaws against longitudinal movement. Pressure applied by the jaw 8 against the tube serves toelTect a collapsing of the tube 6 and resultant dispensing of the contents therein through the discharge port of the latter.

When the rear section of the tube has been completely collapsed as illustrated in Figure 3 the movable jaw 8 is raised to the vertical position illustrated in Figure 2 and the tube moved towards the rear end of the jaws to position an expanded section of the tube between the jaws as illustrated in Figure 6, thereby permitting further dispensing of the contents thereof. In tubes of relatively long length the foregoing operation may be repeated in order to completely dispense the entire contents thereof. Furthermore, the collapsed end of the tube extending beyond the jaws may be severed, the projection l2 coacting with the groove II to crimp the tube adjacent the severed end and seal the same.

From the foregoing it will be apparent that I have provided a simple, efiicient and inexpensive device whereby desired quantities of paste or the like may be readily dispensed from a collapsible tube.

What I claim is:

1. A device of the character described, comprising, a stationary jaw equipped with side walls adapted to receive therebetween a collapsible tube, a movable jaw pivoted to said stationary jaw between said side walls and operable for engaging said tube in a manner to collapse the portion of said tube engaged by said jaws to dispense the contents therefrom, one of said jaws fashioned with a locking groove, the other of said jaws fashioned with a projection whereby to crimp and look a portion of said tube in said groove against displacement while the contents of said tube are being dispensed.

2. A device of the character described, comprising, a stationary jaw equipped with side walls adapted to receive therebetween a collapsible tube, a movable jaw pivoted to said stationary jaw between said side walls and operable for engaging said tube in a manner to collapse the portion of said tube engaged by said jaws to dispense the contents therefrom, and means pivoting said movable jaw to said stationary jaw in a manner to automatically effect relative adjustment of said jaws.

3. A device of the character described, comprising, a stationary jaw equipped with side walls adapted to receive therebetween a collapsible tube, a movable jaw pivoted to said stationary jaw between said side walls and operable for engaging said tube in a manner to collapse the portion of said tube engaged by said jaws to dispense the contents therefrom, one of said jaws fashioned with a locking groove, the other of said jaws fashioned with a projection whereby to crimp and look a portion of said tube in said groove against displacement while the contents of said tube are being dispensed, and means pivoting said movable jaw to said stationary jaw in a manner to automatically effect relative adjustment of said aws.
